Description

Multipurpose CLEANING SOLUTION COMPOSITION with Eco-friendly And Hypoallergenic Properties

The present invention relates to a multi-purpose cleaning composition having eco-friendly and hypoallergenic properties.

As a general detergent, synthetic surfactants are mainly used for cleaning action. However, synthetic surfactants are highly harmful to the human body and have an adverse effect on the environment, so their use is limited. In order to replace synthetic surfactants, research on eco-friendly, hypoallergenic detergents using natural surfactants is being actively conducted.

Since natural surfactants have lower cleaning performance than synthetic surfactants, natural extracts such as citrus extracts such as oranges and lemons containing limonene or limonene are used together. However, as limonene is an allergenic substance, caution is required in product use. Recently, limonene is an allergenic substance, and management of limonene is being strengthened to such an extent that the labeling of the substance on products containing it is mandatory. In addition, according to recent research results, limonene reacts with ozone in the air to change to formaldehyde, a carcinogen, so its use is limited.

Among natural surfactants, nonionic surfactants have very low skin irritation, but have weak cleaning power. In the case of existing products, anionic surfactants or limonene, an allergen, are used to increase cleaning power, but these products have a problem of high skin irritation. Accordingly, there is an increasing need for the development of a natural hypoallergenic detergent that suppresses skin irritation without using allergens or anionic surfactants, and has synergistic effects such as antibacterial and deodorizing properties as well as excellent cleaning performance.

On the other hand, the cleaning agent for cleaning the inside of the house is different from general cleaning agents such as dishwashing detergent, and when cleaning the inside of the house, no additional water cleaning is performed after using the cleaning agent, so that the cleaning agent directly comes into contact with the skin on a dry surface. For this reason, unlike general detergents, it should be safer for skin irritation and should not leave a sticky or slippery residue after natural drying. It is not easy to achieve the desired level of cleaning power, antibacterial power and residual feeling by simply diluting the high-concentration detergent of the prior art.

Prior Art 1 (Korean Patent Publication No. 10-2013-0060265), Prior Art 2 (Korean Patent No. 10-2295942), and Prior Art 3 (Korean Patent No. 10-2266094) relate to a detergent technology containing a natural surfactant or composition It is difficult to apply as a cleaning composition for cleaning the inside of the house in that it is difficult to improve skin irritation and residual feeling because it contains a high content of anti-surfactant.

In the present invention, as a use for cleaning the inside of the house, it contains a nonionic surfactant, a polyhydric alcohol, an organic acid and water, which are the minimum active ingredients in the cleaning composition, and the optimal content ratio of the nonionic surfactant and the polyhydric alcohol among these ingredients An object of the present invention is to provide a cleaning composition that realizes high cleaning power and antibacterial power by applying it and does not leave any residue after drying.

In addition, in the present invention, by using only natural nonionic ingredients such as decyl glucoside and/or coco glucoside without a synthetic surfactant component, to provide a hypoallergenic detergent that suppresses skin irritation and has excellent cleaning performance and synergistic effects such as antibacterial and deodorizing. do.

One embodiment of the present invention is a nonionic surfactant containing an alkyl polyglucoside; polyhydric alcohol; organic acids; and water, wherein the alkyl polyglucoside comprises coco glucoside and/or decyl glucoside, and the sum of the nonionic surfactant, polyhydric alcohol and organic acid: water in a weight ratio of 0.03:99.97 to 5:95 A cleaning composition is provided.

The polyhydric alcohol is a dihydric to tetrahydric alcohol having 6 or less carbon atoms, and a ratio of the number of hydroxyl groups (OH) to carbon atoms may be 0.3 to 1.5.

The polyhydric alcohol may have a water solubility of 50-100 (g/100ml, 20°C).

The composition may include the nonionic surfactant and the polyhydric alcohol in a weight ratio of 1:0.5 to 1:7.

The organic acid is a carboxylic acid having 6 or less carbon atoms, and the ratio of the number of carboxyl groups (COOH) to carbon number may be 0.3 to 1.5.

The organic acid may have a water solubility of 0.5-100 (g/100ml, 20°C).

The composition may include a nonionic surfactant and an organic acid in a weight ratio of 1:0.5 to 1:10.

In the composition, when the polarity of water is 1.0, the relative polarity of the polyhydric alcohol to water and the relative polarity of the organic acid to water may be in the range of 0.85 to 0.55.

The composition may not include at least one selected from the group consisting of thickeners, antioxidants, sequestering agents, and anionic surfactants.

The composition comprises, based on the total weight, 0.01 to 3% by weight of a nonionic surfactant; 0.01 to 3% by weight of polyhydric alcohol; 0.01 to 1% by weight of an organic acid; and the remaining amount of water.

In the present invention, without using allergens or anionic surfactants, it is possible to provide a cleaning solution having a synergistic effect of cleaning power, residual feeling, fragrance, deodorization and antibacterial power by a combination of minimal active ingredients.

Specifically, it does not use anionic surfactants with high skin irritation and limonene, an allergen, and contains cocoglucoside, decyl glucoside, organic acids and polyhydric alcohols to dramatically improve cleaning performance, and furthermore, to realize excellent antibacterial effects. . In addition, since the cleaning composition of the present invention contains extremely low content of active ingredients except for water, there is almost no residual feeling such as stickiness or slippery after natural drying, and skin irritation can be suppressed because only natural ingredients are used.

When the cleaning agent of the present invention is used for cleaning the floor at home, it is easy to keep the house clean. In addition, it does not leave any residue even after multiple use and has excellent directionality, which is advantageous in terms of consumer use. In using the cleaner, there are no harmful ingredients and no residual feeling is felt, so it can easily replace the floor mop cleaning and provides convenient usability. In addition, since the detergent of the present invention is composed of natural substances that do not cause skin irritation and allergies, it has excellent stability as a whole, including those with weak immunity such as infants and the elderly, so car washer fluid, glasses and contact lens cleaning solution It can be used as a main ingredient in various household products such as shampoo, animal cleaner, hand sanitizer for kitchen or restaurant, feminine cleanser, and portable wipes, as well as as a special cleaner such as shampoo.

Advantages and features of the present invention and methods of achieving them will become apparent with reference to the embodiments described below in detail in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in a variety of different forms, only these embodiments allow the disclosure of the present invention to be complete, and common knowledge in the technical field to which the present invention belongs It is provided to fully inform the possessor of the scope of the invention, and the present invention is only defined by the scope of the claims.

Unless otherwise defined, all terms (including technical and scientific terms) used herein may be used in the meaning commonly understood by those of ordinary skill in the art to which the present invention pertains. In the entire specification, when a part "includes" a certain component, this means that other components may be further included, rather than excluding other components, unless otherwise stated. The singular also includes the plural unless the phrase specifically states otherwise.

A cleaning composition according to an embodiment of the present invention will be described. The cleaning composition may include a nonionic surfactant containing an alkyl polyglucoside; polyhydric alcohol; organic acids; and water. In the case of the cleaning composition of the present invention, it has excellent cleaning power and antibacterial power with only a minimum of essential active ingredients, is safe because of very low skin irritation, and has no residual feeling such as stickiness or slippery even after natural drying. may be suitable for use as

The alkyl polyglucoside includes coco glucoside and/or decyl glucoside, and the alkyl polyglucoside may include a C8 to C18 branched or straight chain alkyl group, preferably a C8 to C16 branched or straight chain alkyl group. can do.

Natural nonionic surfactants such as alkyl polyglucosides have very low skin irritation compared to ionic surfactants, but have weak cleaning power. In the prior art, an anionic surfactant or an allergy-inducing substance such as limonene is additionally used to increase the cleaning power of the nonionic surfactant, but it is difficult to lower the skin irritation. In the present invention, by mixing and using a specific natural nonionic surfactant together with a polyhydric alcohol and an organic acid in a specific content ratio, it suppresses skin irritation and provides a natural hypoallergenic cleaning composition having excellent cleaning performance and synergistic effects such as antibacterial and deodorizing. can do.

Meanwhile, the alkyl polyglucoside may include coco glucoside and decyl glucoside, but not lauryl glucoside. Since lauryl glucoside has a relatively low detergency, when an active ingredient is used in a very small amount as in the present invention, the content of lauryl glucoside may be increased or additional additives may be required to increase the detergency, and as a result, polyhydric alcohol in the composition , it is difficult to uniformly mix with organic acids, which may lead to layer separation. Accordingly, it may be difficult to effectively implement a synergistic effect in combination with the active ingredients in the composition, and residues such as some slippery or sticky feeling after natural drying may remain, which is undesirable.

The polyhydric alcohol may be a dihydric to tetrahydric alcohol. For example, it may include at least one selected from the group consisting of butylene glycol, glycerin, ethylene glycol and hexylene glycol, and preferably hexylene glycol such as 1,2-Hexanediol. may include A polyhydric alcohol is a short hydrocarbon complex having at least two hydroxyl groups in one molecule, has a high boiling point, and has a low molecular weight, but has hydrophilicity and lipophilicity. This is suitable for cleaning hard-to-wipe contaminants having low lipophilicity, and can be almost completely removed by rinsing with water, and has the advantage of providing a stable composition in terms of environment-friendliness by minimizing the amount of non-ionic surfactant.

Specifically, the polyhydric alcohol may be a dihydric to tetrahydric alcohol having 6 or less carbon atoms, for example, the ratio of the number of hydroxyl groups (OH) to the number of carbons (C) may be 0.3 to 1.5 or 0.3 to 1. In addition, the polyhydric alcohol may have a water solubility of 50-100 (g/100ml, 20°C), 70-100 (g/100ml, 20°C), or 90-100 (g/100ml, 20°C). Since the polyhydric alcohol of the present invention has a high affinity for water and a high relative polarity, it has good compatibility with other active ingredients and can suppress layer separation in the cleaning composition when mixed. After using the detergent on the contaminated area, almost no residue is left, so there is no slipping or stickiness, as well as excellent dispersibility between active ingredients, which can significantly improve cleaning performance even when a very small amount is included. For example, polyhydric alcohols such as 1,2-heptanediol, 1,2-octanediol, and ethylhexylglycerin have a relatively low OH/C number ratio of 0.3 or less, and a water solubility of 50 g/100 ml or less or 1 g/100 ml or less. It is low, so even if a very small amount is used, the performance may be slightly deteriorated.

The composition includes the nonionic surfactant and the polyhydric alcohol in a weight ratio of 1:0.5 to 1:7, preferably 1:0.5 to 1:5, 1:0.7 to 1:5, or 1:0.8 to 1:4.5 can be included as When the weight ratio of the polyhydric alcohol to the nonionic surfactant is remarkably low (less than 1:0.5), there is a fear that the functionality including the ability to remove foreign substances, antibacterial power and preservative power may be reduced. In addition, if it exceeds 1.:7, non-volatile residues may be generated, and compatibility with other components may decrease, resulting in poor product stability.

The organic acid may include at least one or at least two selected from the group consisting of acetic acid, citric acid, malic acid, and succinic acid, preferably including acetic acid. have. By including an organic acid together with other components in the cleaning composition of the present invention, it is possible to implement a synergistic effect of antibacterial and deodorizing functions. Organic acids are weak acids compared to inorganic acids, and even after drying, they are less irritating when in contact with the skin, and are effective because they can reduce the possibility of causing corrosion to household items when used at home. In addition, it can be extracted from natural substances, and it is eco-friendly because of its excellent biodegradability even when discarded. The organic acid according to the present invention is a carboxylic acid having 6 or less carbon atoms, and since it has a low molecular weight among organic acids, it has high solubility in water and excellent productivity and safety. In particular, acetic acid, unlike other organic acids, is a volatile liquid and does not remain in the object to be cleaned even after drying, so that it does not remain after washing several times. In addition, when the acetic acid contained in a small amount is volatilized, it is preferable because there is an advantage that a deodorizing effect can be additionally obtained. Acetic acid can be replaced with vinegar ingredients such as apple cider vinegar or brown rice vinegar, and it is harmless to the human body.

Specifically, the organic acid may be a carboxylic acid having 6 or less carbon atoms, and the organic acid may have a ratio of the number of carboxyl groups (COOH) to the number of carbons (C) of 0.3 to 1.5 or 0.3 to 0.8. In addition, the organic acid has a water solubility of 0.5-100 (g/100ml, 20 ℃), 10-100 (g/100ml, 20 ℃), 30-100 (g/100ml, 20 ℃), 50-100 (g / 100ml, 20℃) or 65-100 (g/100ml, 20℃). For example, the solubility of polyhydric water such as malic acid and succinic acid is somewhat low, such as 60 g/100 ml or less or 1 g/100 ml or less, so that even if a very small amount is used, the performance may be slightly deteriorated.

The composition may include the nonionic surfactant and the organic acid in a weight ratio of 1:0.4 to 1:10, preferably 1:0.8 to 1:6 or 1:1 to 1:4. When the weight ratio of the organic acid to the nonionic surfactant is less than the set range, the cleaning power may be reduced, and if it exceeds the set range, it is difficult to be applied as a cleaning composition due to the odor and strong acidity of the organic acid itself.

In the composition, when the polarity of water is 1.0, the relative polarity of the polyhydric alcohol to water and the relative polarity of the organic acid to water may be in the range of 0.85 to 0.55. The polyhydric alcohol and the organic acid have high water solubility, and at the same time, the relative polarity difference is not large, so that uniform mixing is possible without layer separation in the composition. Due to these characteristics, it is easy to dry and remove with water, so it may not remain in the object to be cleaned.

In the composition according to the present invention, when the polarity of water is 1.0, the relative polarity of the polyhydric alcohol to water may be in the range of 0.85 to 0.55 or 0.85 to 0.75. In particular, at least one selected from the group consisting of ethylene glycol, propylene glycol, 1,3-butanediol, 1,2-hexanediol and glycerin among the polyhydric alcohols or 1,2-hexanediol (relative polarity = 0.79~ 0.81) is preferable in terms of the relative polarity index for water.

In the composition according to the present invention, when the polarity of water is 1.0, the relative polarity of the organic acid to water may be in the range of 0.85 to 0.55 or 0.70 to 0.60. In particular, among the organic acids, at least one selected from the group consisting of acetic acid and citric acid or acetic acid (relative polarity = 0.648) is preferable in view of the relative polarity index to water.

The composition according to the present invention may further comprise an essential oil. The essential oil has the advantage of further improving the performance of the cleaning composition, such as fragrance and antibacterial power. The essential oil may have a content in the composition of 0.001 to 0.01% by weight. If it is out of the above range, it is difficult to implement the above-described effect, and the fragrance may be weak or phase separation may occur. The type of the essential oil is not particularly limited, but may preferably include Keyuput oil, peppermint oil, and the like.

On the other hand, the detergent composition of the present invention may not contain at least one, at least two or at least three selected from the group consisting of a thickener, an antioxidant, a sequestering agent, and an anionic surfactant, and a thickener, an antioxidant, a metal It may be one that does not contain a sequestering agent and an anionic surfactant. In the case of the cleaning composition of the present invention, when the above ingredients are included in the cleaning composition of the present invention, it is difficult to uniformly mix the nonionic surfactant, organic acid and polyhydric alcohol in the composition, so the cleaning power may be reduced. It may be undesirable in terms of residual feeling such as stickiness.

The detergent composition may include the nonionic surfactant, the polyhydric alcohol, and the organic acid in a weight ratio of: 0.03:99.97 to 5:95 by weight, for example, 0.03:99.97 to 1:99 by weight, 0.05 It may be preferable when included in a weight ratio of: 99.95 to 0.2:99.8 or 0.05:99.95 to 0.1:99.9.

Meanwhile, the composition may include 0.03 to 5% by weight of the total of the nonionic surfactant, the polyhydric alcohol, and the organic acid based on the total weight, for example, 0.03 to 1% by weight, 0.05 to 0.2% by weight. Alternatively, it may be preferable when it is included in an amount of 0.05 to 0.1% by weight.

The cleaning composition of the present invention is for cleaning the inside of a house, and is different from general cleaning agents such as dishwashing agents in the technical area. In the case of the present invention, since the cleaning solution is applied to the contaminated surface and used, additional water washing (cleaning) is not performed, so that the cleaning solution is directly in contact with the skin on the naturally-dried surface. Accordingly, unlike general cleaners that require additional washing with water, skin irritation should be extremely low, and residues such as stickiness or slippery should not remain after natural drying. For this purpose, the active ingredients included in the cleaning composition should be used to a minimum. However, the cleaning composition of the present invention cannot be easily achieved by simply diluting a high-concentration cleaning agent such as a general dishwashing agent.

The composition comprises, based on the total weight, 0.01 to 1% by weight of a nonionic surfactant; 0.01 to 0.5% by weight of polyhydric alcohol; 0.01 to 1% by weight of an organic acid; and the balance of water, for example, 0.01 to 3% by weight, 0.015 to 1% by weight, 0.025 to 1% by weight, 0.1 to 0.5% by weight, or 0.15 to 0.35% by weight of a nonionic surfactant; 0.01 to 3% by weight, 0.02 to 1% by weight, 0.02 to 0.5% by weight, 0.02 to 0.3% by weight or 0.02 to 0.2% by weight of a polyhydric alcohol; 0.01 to 1 wt%, 0.01 to 0.5 wt%, 0.01 to 0.3 wt%, 0.02 to 0.2 wt%, 0.02 to 0.1 wt% or 0.02 to 0.07 wt% organic acid; and/or the remainder of water. Accordingly, the above-described effect can be further improved. In addition, when the content of the organic acid is less than the above range, the cleaning power may decrease, and if it exceeds the organic acid content, the smell of the cleaning composition may not be good due to the scent of the organic acid itself. If the content of the nonionic surfactant is less than the set range, the cleaning effect is reduced, and on the contrary, if it exceeds the set range, a residual feeling may remain after natural drying, which is not preferable. On the other hand, when the content of the polyhydric alcohol is within a numerical range, the cleaning effect may be optimized.

Hereinafter, the present invention will be described in detail by way of Examples, but these are for describing the present invention in more detail, and the scope of the present invention is not limited by the Examples below.

Example

(Examples 1-1 to 7-2 and Comparative Examples 1-1 to 3-5)

A cleaning solution sample was prepared by mixing the raw materials with the composition shown in Tables 6 to 13, and this was used in the subsequent experimental examples (unit: wt%).

Experimental example

The cleaning power, residual feeling, fragrance and antibacterial power were evaluated by applying the following measuring method to the prepared liquid detergent composition.

1) Evaluation of cleaning power

A thin layer of red pepper oil was applied as a contaminant to a height of 1 cm on the object to be cleaned with a width of 1.5 cm, and the detergent was sprayed 10 times with a dropper for washing. After the object to be cleaned was completely dried, 0 to 3 points were evaluated 10 times to calculate an average score and graded accordingly to evaluate the cleaning power. The results of evaluation of the cleaning power of the detergents prepared in Example 1-1, Comparative Example 1-4 and Comparative Example 1-2 are shown in FIG. 1 .

Evaluation contents (evaluation score) Evaluation standard Insufficient (0.0~1.5 points) Oil contamination is widely distributed and red color is easy to identify Moderate (1.6-2.5 points) Oil contamination is locally distributed and red color is difficult to identify Excellent (2.6~3.0 points) It is difficult to identify the remaining oil contamination, and the red color is impossible to identify.

2) Residual evaluation

After wiping a large area of the object to be cleaned with a cloth soaked in detergent and completely drying it, the feeling of residual was evaluated with an average score by touching it with a hand 10 times according to the following evaluation criteria.

Evaluation contents Evaluation standard Inadequate Slippery or sticky feeling is strongly felt usually Weak feeling of slippage or stickiness Great Does not feel slippery or sticky

3) Flavor evaluation

The fragrance was subjectively evaluated by smelling the fragrance of the detergent itself.

4) Evaluation of antibacterial activity

Staphylococcus aureus was tested according to the ASTM E2149 test method (measurement of the antibacterial activity of an antimicrobial agent immobilized under dynamic contact conditions), and the antimicrobial activity was evaluated according to the following evaluation criteria.

Evaluation contents Evaluation standard Inadequate Antibacterial activity less than 90.0% usually Antibacterial power 90.0~95.0% Great Antibacterial power 95.0~99.0% very good Antibacterial activity 99.0~99.9%

(Unless otherwise stated in Table 6 above, the numerical value of each component means wt%)

In Table 6, it was confirmed that the cleaning compositions of Examples 1-1 and 1-2 were prepared including all of a nonionic surfactant, a polyhydric alcohol, and an organic acid, and had a synergistic effect of cleaning power, residual feeling, fragrance and antibacterial power. could

It was analyzed that the cleaning compositions of Comparative Examples 1-1 and 1-2 did not contain an organic acid or polyhydric alcohol, and thus the cleaning power and antibacterial power were significantly deteriorated compared to Examples.

In the case of the cleaning composition of Comparative Example 1-3, there was no improvement in cleaning power according to the mixed use between the active ingredients. This result is analyzed because the self-cleaning power of lauryl glucoside is low and the layer separation in the composition is accelerated due to uneven mixing with 1,2-Hexanediol and acetic acid.

Limonene used in the cleaning composition of Comparative Examples 1-4 is recently an allergen, and management of limonene has been strengthened to such a degree that labeling of the substance for products containing it is mandatory. Its use in cleaning compositions is not preferred as it can be converted to aldehydes.

(Unless otherwise specified in Tables 7 and 8 above, the numerical value of each component means wt%)

In Tables 7 and 8, it was confirmed that the cleaning composition of the present invention exhibits synergistic effects such as excellent cleaning power and residual feeling due to the combination of ingredients when diluted so that the total amount of cleaning liquid components falls within the desired numerical range. , these results suggest that it is difficult to predict the performance after dilution from the performance evaluation of commonly used high-concentration cleaning solutions.

The cleaning liquid (concentrate) of Comparative Example 2 used as a general dishwashing agent had very good cleaning power, but it was confirmed that the cleaning performance measured after dilution to the level of Example 2 (100-fold dilution) was very deteriorated. In addition, it was also confirmed that the residual feeling such as stickiness or slippery was not sufficiently removed after natural drying only by simple dilution. That is, it was found that it was difficult to achieve the performance of the cleaning composition of the present invention by simply diluting the high concentration cleaning agent of Comparative Example 2.

In Table 9, in the cleaning compositions of Examples 3-1 to 3-5, the weight ratio of the surfactant to the polyhydric alcohol falls within the numerical range of the present invention, and the cleaning compositions of Comparative Examples 3-1 to 3-4 do not. It exhibited excellent cleaning performance compared to that.

When referring to the cleaning compositions of Comparative Examples 3-1 and 3-2, when the weight ratio of 1,2-hexanediol to glucoside is significantly lower than 1:0.5, it is analyzed that the cleaning performance is lowered, and Comparative Example 3-3 And when referring to the cleaning composition of 3-4, when the weight ratio of the surfactant to the alcohol exceeds 1:7 and is excessively high, it is analyzed that the cleaning performance is deteriorated due to poor compatibility with other active ingredients in the composition.

Referring to Table 10, the cleaning composition of the present invention can improve cleaning performance by including an organic acid as an active ingredient. On the other hand, it is analyzed that malic acid and succinic acid have low water solubility unlike other organic acids such as acetic acid, so that the layer separation in the composition occurs, the uniformity of mixing in the composition decreases, and as a result, the detergency synergistic effect combined with the active ingredients in the composition does not appear.
